Examples

The following code example demonstrates how to set the DefaultValue, Type, and Direction properties of Parameter objects when using them as output parameters and return value parameters with a stored procedure. This code example is part of a larger example provided for the SqlDataSourceStatusEventArgs class overview.

<asp:sqldatasource
    id="SqlDataSource1"
    runat="server"
    datasourcemode="DataSet"
    connectionstring="<%$ ConnectionStrings:MyNorthwind%>"
    selectcommand="getordertotal"
    onselected="OnSelectedHandler">
    <selectparameters>
      <asp:querystringparameter name="empId" querystringfield="empId" />
      <asp:parameter name="total" type="Int32" direction="Output" defaultvalue="0" />
      <asp:parameter name="_ret" type="Int32" direction="ReturnValue" defaultvalue="0" />
    </selectparameters>
</asp:sqldatasource>

<asp:sqldatasource
    id="SqlDataSource1"
    runat="server"
    datasourcemode="DataSet"
    connectionstring="<%$ ConnectionStrings:MyNorthwind%>"
    selectcommand="getordertotal"
    onselected="OnSelectedHandler">
    <selectparameters>
      <asp:querystringparameter name="empId" querystringfield="empId" />
      <asp:parameter name="total" type="Int32" direction="Output" defaultvalue="0" />
      <asp:parameter name="_ret" type="Int32" direction="ReturnValue" defaultvalue="0" />
    </selectparameters>
</asp:sqldatasource>

Remarks

The type can be used to create strongly typed parameters, so that values are converted correctly between your Web application and underlying code.

If the type of the parameter is changed, the OnParameterChanged method is called.
